Bolink Chain Drive

Post by coxbros1 »

Converting this old Bolink electric funny car to a .21 Chain Drive unit...it is an old Max Power (Novarossi) 3.5cc on-road race engine I had laying around...gonna run it on 50% nitro...Chain Drive will be designed by Dadio Designs 🇬🇧....it will use a Kyosho Optima chain....clutch is from a vintage Losi 8ight buggy...so far I haven't spent any money and just used stuff I had laying around...hopefully it stays that way (minus the chain drive)...yes it has brakes.

Got is all done thanks to Dadio Designs!....then I realized I mounted the engine wrong, it's running in reverse in this location, has to be flipped to the other side...somebody please help me deal with this..Please!
...I ordered a new chassis, not a huge deal but the body cutout for the exhaust is...I got some serious work ahead of me 😨🤦

If a jobs not worth doing then its certainly not worth doing well.

Genius.

Beats my idea, which was to mount a Civic body on it backwards and pretend you always intended to make it FWD.

Yay! A chance to break out the Crayons!

👆 One way to reverse the direction of the wheel rotation would be to install a forward idler gear and two idlers adjacent to the motor, then run the chain over the top of the drive sprocket.

👇 Another way would be to install two idlers and run the chain on the front side of the driven sprocket, which would also reverse the direction of wheel rotation.

Or you could ditch the DD and use a combo of gears and sprocket on a jack shaft. Either engine sprocket to spur sprocket to pinion gear to spur gear on wheel/axle....or the more common engine pinion to spur gear to pinion sprocket to spur sprocket on wheel/axle.
